(c)        The material should be strong and capable of resisting superimposed loads/pressure on it.

(d)       Material should be flexible, so in which it could accommodate the structural movements without any fracture.

(e)        The material should not be costly.

(f)        The material should be like that leak-proof jointing is probable.
